So why did I get an email supposedly from
payments...@google.com asking me to change the credit card used to fund my Google Cloud Platform?
This email went on to claim that my credit card last (4 numbers shown) would be expiring soon.
However when I looked at my Google account I saw that the credit card shown in that email was not the card that was actually listed to pay the GCP account?
Only Google know why such emails are being sent but it does mean I will be paying lees attention to future Google emails (or consign them to spam with the rest of the phishing emails)
